Description
Technical Field

[0002] A thermal switch is a device that uses the different thermal expansion coefficients of the various component layers of a bimetallic strip. When the temperature changes, the deformation of the active layer is greater than that of the passive layer, so that the bimetallic strip as a whole will bend toward the passive layer. The curvature of the composite material changes, resulting in deformation, thereby realizing the current on and off. The thermal switch is also called a temperature switch, and its principle is the bimetallic principle. Generally, electrical appliances with heating use this component, such as the temperature control switch of a kettle, the starter of a fluorescent lamp, etc. The existing temperature correction device of a thermal switch can basically meet the daily use needs, but there are still some shortcomings that need to be improved.
[0003] The existing temperature correction device of the thermal switch usually adopts electric heating or water bath heating when in use.

For this reason, we propose a temperature correction device for the thermal switch to solve the above problem. Utility Model Content
